Piper Jaffray analyst William Quirk upgraded Masimo to Overweight with an unchanged price target of $120. Management, during recent meetings, was upbeat about their near- and longer-term prospects of driving 8%-10% sales growth, at least 100 basis points of operating margin improvement and the company's 30% operating profit goal, Quirk tells investors in a research note. The analyst believes Masimo can drive leverage in excess of that in 2019 based on several existing and new initiatives started in 2018. The company is "set for a period of sustainable top- and bottom-line growth," says Quirk.
